Many of users do not use powerful Maxima computer algebra system for systematic work, but for ad hoc algebraic calculations – equations, functions, matrixes, etc. only. To do this job, it is not useful to download the whole application from a web site.
Function: content (<p_1>, <x_1>, ..., <x_n>) Returns a list whose first element is the greatest common divisor of the coefficients of the terms of the polynomial <p_1> in the variable <x_n> (this is the content) and whose second element is the polynomial <p_1> divided by the content.

Examples:
(%i1) content (2*x*y + 4*x^2*y^2, y);
2
(%o1) [2 x, 2 x y + y] There are also some inexact matches for content. Try ?? content to see them.
